Chapter 6, Problem 6.57E

Interpretation Introduction

Interpretation:

The molecular weight of the given gas is to be calculated. Whether the given sample of gas is $\text{He}$, $\text{Ne}$, or $\text{Ar}$ is to be identified.

Concept introduction:

The ideal gas equation is used to represent the relation between the volume, pressure, temperature and number of moles of an ideal gas. The ideal gas equation is given as,

$PV=nRT$

Where,

• $V$ represents the volume occupied by the ideal gas.

• $P$ represents the pressure of the ideal gas.

• $n$ represents the number of moles of the ideal gas.

• $T$ represents the temperature of the ideal gas.

• $R$ represents the ideal gas constant with value $0.08206\text{L}\cdot \text{atm}/\text{K}\cdot \text{mol}$.
